Hey andyadvice ,
Thanks for reaching out to us!
Good question! I think the most simple option is by duplicating the group and keep one only visible on desktop and one only visible on mobile phones.
Then, for the mobile-duplicated group, you can attach a page-rule to hide it on that specific page.
This means that the desktop-group will be visible on all pages, but only on desktop. The mobile-group will only be visible on desktop and on specific pages.
Let me know if this helps 🙂
